As we are all aware, there are many leaked OS's out here now.
So let's say I want to load a new OS, what would be the best way to proceed for the cleanest device?
Of course the full backup, but after that....
Should I....
Reload original software, then load new OS or does loading the original software matter.
AND....
Should I do all this with or with out my SD card in?
Thanks for your thoughts n this in advance!
